RESUMO

Objectives: To verify the effect of intravelar veloplasty associated with secondary palatoplasty on the speech of patients with velopharyngeal insufficiency (VPI) and to compare the speech outcomes among these patients, according to the extent of defect of velopharyngeal closure as analyzed by nasopharyngoscopy. Model: Prospective study of patients with repaired cleft palate and residual VPI, evaluated at 3 days before and 8 months after surgery in the average, who were divided into two groups: one with minor defect and the other with medium to large defect in velopharyngeal closure. Differences between groups and stages were considered significant at the 5% level. Setting: Laboratory Physiology of Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP). Participants: 40 patients of both genders, aged 4 to 48 years old, being 25 with minor defects (group I) and 15 with medium to large defects (group II) in velopharyngeal closure. Variables: Hypernasality, nasal air emission, compensatory articulation production and velopharyngeal function, evaluated by perceptive evaluation of speech and nasalance obtained by nasometry. Results: After surgery, group I exhibited elimination of hypernasality, nasal air emission and compensatory articulation production in 64%, 64% and 20% of patients, respectively. Adequate velopharyngeal function and normalization of nasalance values were observed in 44% of cases in this group. Group II presented elimination of hypernasality in 13%, nasal air emission in 20% and compensatory articulation production in 7%. Only 7% of patients in this group presented adequate velopharyngeal function and 14% exhibited normalization of nasalance after surgery. Conclusions: In the short term, intravelar veloplasty associated with secondary palatoplasty led to improvement in VPI-related speech symptoms in most patients. The results further demonstrated that surgery allowed greater improvement in patients presenting minor defects in velopharyngeal closure.
